Alternate Universe - Medieval — Tag Meaning
Sends characters back to castles, keeps, and muddy villages — knights and squires, lords and healers, tourneys and sieges. It overlaps heavily with fantasy AUs but can stay strictly historical, and the era's oaths and fealty give writers a vocabulary of devotion that modern settings can't match: a knight kneeling is worth a dozen love confessions.

Alternate Universe - Historical
The catch-all for any past-era relocation that doesn't have its own decade or period tag — ancient empires, the Renaissance, frontier towns, revolutionary barricades. Authors range from meticulous researchers footnoting their hairpins to vibes-first storytellers, and the tag itself promises only that the present day has been left behind.

Alternate Universe - Vikings
Sails the cast into the Norse world of longships, raids, jarls, and skalds — sometimes rigorously historical, sometimes braided with Norse mythology until gods walk among the raiders. Captive-and-captor romance and shield-brother devotion are recurring structures, and the era's honor culture gives conflicts a sworn, blood-feud weight.
